The test is administered on a sliding scale based on age. If a young child answers 5 questions incorrectly in one section, then the rest of the questions in that section are skipped. The questions go in order from easiest to hardest so the youngest children are only expected to answer a few in each section. The scoring mechanism is also based on the child's age, so young children are scored much easier than older children.

We based our test and scoring algorithm on the test scores of over 2,000 children from age 6 to 16. The test was created and validated by our PhD-level psychologists.
